Choosing between bifold doors and sliding doors is one of the biggest decisions you'll make when opening up your home to the garden. Both are excellent options, but they suit different situations. Here's an honest comparison to help you decide.
The Key Differences at a Glance
| Feature | Bifold Doors | Sliding Doors |
|---|---|---|
| Clear opening | Up to 90% of the width | Typically 50-66% |
| Frame width | 30-50mm per panel | 20-35mm |
| Price (3m, typical project cost) | £2,900-£4,500 | £3,500-£5,500 |
| Space needed | Panels stack to one side | Panels slide behind each other |
| Best for | Wide openings, entertaining | Minimalist design, tight spaces |
When Bifold Doors Are the Better Choice
You want the widest possible opening. Bifold doors fold and stack neatly to one or both sides, giving you up to 90% of the opening width completely clear. This creates a genuine indoor-outdoor connection that's hard to beat for summer entertaining. You have a standard-width opening. For openings of 2.4m to 5m, bifold doors are the most popular and cost-effective option. They come in 3 to 7 panel configurations to suit virtually any width. Your home style is traditional or transitional. Bifold doors suit a wider range of architectural styles, from Victorian terraces to modern extensions.When Sliding Doors Are the Better Choice
You want the slimmest possible frames. Sliding door profiles can be as narrow as 20mm — significantly slimmer than bifold equivalents. When closed, you see more glass and less frame. Space is limited on one or both sides. Bifold panels need room to stack when open. If your opening leads onto a narrow patio or the panels would obstruct a walkway, sliding doors are the practical choice. You prefer a minimalist aesthetic. Sliding doors offer the cleanest, most architectural look when closed. With fewer vertical bars breaking up the glass, they create a more dramatic wall-of-glass effect. You have a very wide opening. For openings over 5m, large-format sliding doors (especially lift & slide systems) can handle the scale more elegantly than a long run of bifold panels.The Verdict
There's no universally "better" option — it depends on your priorities:
- Choose bifold if you want the widest opening, the best value for standard widths, and a versatile style
- Choose sliding if you want the slimmest frames, the most minimalist look, or space-saving operation
